IMPROVED GAS APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I JAMns F. SPENCE, of Williamslmrg, in thecouuty of Kings, and State of New York, have invented a new and improved Gas Apparatus; and I do hereby declare that the following is'a full, clear, and exactdescripti'on thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a transverse vertical section of this invention. the line .r, fig. 2, indicating the plane of section.

Figure is a longitudinal vertical sectionot the same taken in'the plane indicated by the line 3/ y, fig. 1.

Similar lctters of reference indicate like parts.

This invention consists in the arrangement of a series of S-shapcd pipes in the interior of a hollow drum. which revolves in the "interior of a vessel partially filled with oil,:in combination with a suitable oil-supply pipe and with a steam pipe, in such a manner that by the action of the steam the oil or volatile hydrocarbon liquid in the vessel is vaporized, and as the drum revolves a mixture of steam and hydrocarbon vapors is blown out through the S-sha-ped pipes in the upper space of the outer vessel. whence it'is conducted through suitable pipe to the burners;

i A represents a vessel made ofsheet metal, or any other suitable material, in cylindrical or any other desirable form onshapei The ends or heads of this vessel form the bearings for a shaft, B, to which a slow revolving motion is imparted by suit-able power, and on which is mounted a hollow cylindrical drum, C. The diameter of this drum is such that an annular space is left between its outers urface and the inner surface of the vessel A, and a suitable pipe, D, passes through one of the heads of the vessel A and. through a circular opening, a, in'the centre of one of the heads of the drum C, where. it rises up, as clearly shown in the drawing.

Through this pipe steam is introduced, and another pipe, E, serves to admit to. the vesscl A and drum 0 the requisite supply of hydrocarbon liquid. This pipe extends down from a tank, F, which is closed, air-tight, and it terminates in the vessel A at the desired level of the hydrocarbon liquid. As .soon as the level of this liquid closes the mouth of the pipe the supply stops, but when the level sinks below saidmouth afresh supply of hydrocarbon liquid is admitted,.and by these means the apparatus is rendered self-supplying. From the shaft B extend a series of S-shaped pipes, G, which are pen at both ends, as shown in fig. 1 of the drawings, and a pipe, H, which emanates from the upper part of the vessel A, serves to carry off the gas or mixture of steam and hydrocarbon vapor.

The operation is as follows: As the drum 0 revolves slowlythc inner ends of the S-shapcd pipes G are success ively raised above the level of the oil in said drum, and the steam which accumulates in the upper part of said drum is permitted to blow through said pipes. The steam being in contact withthc surface of the hydrocarbon liquid is saturated with vapors thereof, and in moving through the S shaped pipes it comes in contact with a small body of liquid contained therein, and by vaporization thcreotit is sol-charged with hydrocarbon vapors, vso that a good illuminating mixture obtained, which, when admitted through the pipe H to suitable burners, will give a brilliant light.

By this apparatus a very cheap light can be pl'oduccthht'hich is particularly convenient for manufactories,

or other establishments where steam is on hand, and such establishments are thereby enabled to produce their own gas'at a comparatively trifling expense. Any condensation taking place in the apparatus er'pipcs canbe drawn off by suitable means. i I

What I claim as new, and desire to secure by Letters Patent, is-

The S-shapcd pipes G, in combination with the revolving hollow drum 0, vessel A, steam pipe D, and liquidsupply pipe E, all constructed and operating substantially as and for the purpose described.

The above specification of my invention signed by me this. 20th day of January,.1866.
